Pre-mix. Reed valves. Expansion chambers. All three are terms new, or even relatively new motorcyclists won’t recognize, as the two-stroke engine gives way to the cleaner-burning, yet less efficient, four-stroke. Thankfully, the two-stoke is living on in the dirt world, and this captivating video by Adam Riemann entitled “The Power Of Sound” captures exactly what makes the two-stroke so special.
Admittedly, it’s a bit long at just over 10 minutes, but it’s a fun watch from beginning to end. It starts off with a quick, yet informative explanation of the basic two-stroke engine. From there it’s action packed, as Riemann and Toby Price flog the versatile KTM 300EXC through jumps, whoops, rocks, water crossings, single track and more. All the while the distinct sound of the two-stroke engine exhaust comes shining through.
You can watch the video below. We think the combination of excellent cinematography and great riding make this video one we’ll watch over and over. What do you think? Tell us in the comments section below.
